What this source is
NARA's Catalog API v2 (catalog.archives.gov/api/v2) serves the nation's archival records, including DoD imagery transferred for preservation — an archive of record, not a publication stream.

- Registry notes
- Evaluated 2026-07-28 in the multi-modal survey: documented API (key by email to [address withheld], 10,000 queries/month default) but archival by nature — nothing it publishes constitutes a new government action on a given day. Revisit only for deliberate historical-context or backfill features.
How we ingest it
- Channel
- API
- Method
- Not applicable to the daily flow — archive, not news-flow.
- Request budget
- the agency class: at most 1,500 requests per day shared across every agency web source, counted from the fetch log (failed requests count too)
- Politeness
- robots.txt is honored as observed — including each host's crawl-delay, exactly — and every request identifies itself as fapd/0.1 (Free Agentic Publication Digester; +https://fapd.info/bot.html; contact: hustleyourcity@gmail.com); a refusal is recorded, never evaded
- Capture and hash
- captured raw content is hashed (SHA-256) into the day's committed provenance manifest, hash-chained day to day (PROVENANCE.md)
